Back pain and Braxton hicks gettin worse

Hannah
So I'm a FTM and so not 100-% sure what everything is supposed to feel like but last night I woke up several different times throughout the night with what I'm 99% sure are Braxton hicks, they were painful but irregular. Even this morning I seem to be getting waves of them. I also have lower back pain. Could this be a sign of labor or am I getting my hopes up too early? I'll be 38 weeks on Monday...
